We have a great news for the LG G Flex owners. TWRP recovery is now available for it – F340K model to be exact. Everything works on it. To flash it, first get the img file from here.
Then, download Flashify and boot into recovery. For that, power off the device and use Volume up + power button simultaneously. You will get a scrolling effect and then you will enter recovery. Everything should work like a charm.
For those who do not know about TWRP, it is basically a touch optimized version of CWM (clock work mod).
